IUMIDIFIER FOR nADIA'rons AND THE LIKE.

Application filed February 21, 1917. Serial No. 150,240.

andpthe like, of which the following is a specification.

The present invention has to do with certain improvements in humidifiers for radiators and the like. The humidifier herein disclosed is so constructed that it receives its water automatically from the radiator,

and is thus automatically replenished from time to time. It may also serve to vent the radiator, and thus keep the same free from air at all times.

One of the objects of the invention is to provide a very simple form of device for accomplishing the foregoing as well as other results, and to provide a device of this type which can be very cheaply manufactured from a small number of parts. Also to provide a device so simple 1n construction and operation that it will not readily become disarranged or get out of order.

Other objects and uses' of the invention will appear from a detailed description of the same which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawing:

Figure 1 shows a cross section of our im proved humidifier as the" same may be readily applied to a radiator of familiar form; and

Fig. 2 shows a section taken on thed'ine 22 of Fig. 1', looking in the direction of the arrows.

In the drawing, we have illustrated certain of the radiator coils diagrammatically by the numerals 3 and 4, the coil 4 being the end coil to which it is customary to attach or connect the air vent. The humidifier proper comprises a longitudinal trayor trough 5 into which extends one portion of a wick or the like 6. In the particular construction illustrated, said wick extends upright from the-trough, and the lower end of'the Wick lies within the trough.

The trough itself may be. conveniently connected to. or supported by one or more of the radiator coils as by means of -U-bolts or straps 7 and 8.

Specification of Letters Patent.

'of construction both the chamber and vthe Patented July 23, 1918.

trough may be formed or constructed integrally. A cap or cover 11 seats over and closes the upper end of the chamber 9 and protects the valve mechanism contained therein. n

The numeral 12 designates a boss or ,enlargement on the end .coil of the radiatorinto which it is customary to connect the air vent. In practising the features of our invention. we connect a pipe 13 to the r'adiator, and this may be conveniently accomplished by removing the air vent and connecting the pipe 13 into the boss 12. The

lower end of the pipe -13 connects to the chamber 9 by a universal coupling 14. Within this con ling there is arranged a pin valve 15- which connects to one end of a lever arm 16'pivoted to a stationary'part at the point 17 Afloat 18 on the other arm of the lever 16 serves to control the movements of said lever and thus serves also to move the pin valve 15 back and forth. Manifestly' this arrangement will serve to close the valve15 as soon as the water level within the chamber 9 hasrisen to the desired elevation. In this way, the supply of water to the chamber 9 and to the trough 5 will be automatically controlled by the float valve so as to maintain a substantially c0nthat this device will serve not only as an 100 automatic humidifier but also as an automatic air vent.

In some cases it maybe desirable to provide a hand operated valve 19 in the pipe 13, so that the humidifier may be shut off 105 and thrown out of service. Also in other cases it may be desirable to connect an air vent of the ordinary type20 into the pipe 13, and this may be conveniently done at any: point between the radiator and the 110 valve 19.

While we have herein shown and described only a single embodiment of our invention,

still it will be understood thatwe do not limit ourselves to the said construction, except as we may do so in the-claim. 1'

We claim: 7 1 A humidifier fora radiator comprising an elongated trough having its top open, a capillary wick standing in the trough and drawing moisture therefrom, a valve com-' partment at one end of the trough and in communication therewith by way of a slotted opening, the lower edge of which'opening 1s at such an elevation as to permit the flow of water from the valve compartment into the trough, a valve in the lower portion of the compartment, a float within the compa'rtment and operatively connected to the valve to close the same when the level of the water within the trough reaches the desired point, and a tube connecting the valve with the radiator at a point of. higher elevation than the valve, substantially as and for thepurpose described.
